Blog Ping for Squidoo Lenses. This Ping Tool will notify a number of blog search services that your lens has been updated, and is specially optimised for Squidoo.
It is not certain whether or not this has any benefit or not for existing lenses, but it is probably good for getting new lenses indexed quickly by search engines. Access to this ping tool is also available from the Advanced Dashboard. Note: You are only permitted to ping a lens that has been recently updated. Ping-o-Matic! Blog and ping.
